The aim of this work was to investigate the applicability of non-destructive techniques in monitoring freshness decay of fresh-cut Lamb’s lettuce (Valerianella locusta Laterr.) during storage. Fresh-cut Lamb’s lettuce samples were purchased in a local market the first day of commercialization and stored at two different temperatures (4 °C and 20 °C) up to 10 and 7 days respectively. The quality decay of samples was evaluated by chemical (pH and humidity), physical (texture) and nutritional (phenolic content and antioxidant power) parameters and by non-destructive sensory (electronic nose) and optical (vis/NIR and fluorescence) devices. Results demonstrated that electronic nose, vis/NIR technique and fluorescence could support the conventional techniques in the shelf-life assessment of fresh-cut Lamb’s lettuce providing information useful for a better management of the product along the distribution chain.

Abstract
The aim of this work was to investigate the applicability of non-destructive techniques in monitoring freshness decay of fresh-cut Lamb’s lettuce (Valerianella locusta Laterr.) during storage. Fresh-cut Lamb’s lettuce samples were purchased in a local market the first day of commercialization and stored at two different temperatures (4 °C and 20 °C) up to 10 and 7 days respectively. The quality decay of samples was evaluated by chemical (pH and humidity), physical (texture) and nutritional (phenolic content and antioxidant power) parameters and by non-destructive sensory (electronic nose) and optical (vis/NIR and fluorescence) devices. Results demonstrated that electronic nose, vis/NIR technique and fluorescence could support the conventional techniques in the shelf-life assessment of fresh-cut Lamb’s lettuce providing information useful for a better management of the product along the distribution chain.Pubblicazioni consigliate
